ADJUSTABLE VISE FOR I-IACKSAWS.

. To all whom it may concern:

Be it known that I, AMos HU'rroN, a ribject of the King of GreatBritain, residing in Springfield, in the county of I-Iampden,

in the State of Massachusetts, have invented certain new and usefulImprovements in Adjustable Vises for I-Iacksaws, of whlch the followingis a specification.

This invention relates to an adjustable device for hack saw machines.Among its advantages may be mentioned that my vise willtake work of allsizes and will further locate this work at any point along the hack saw.This is important for the reason that it is desirable to change theworking portions of the saw occasionally; if the saw has been usedconsiderably near its toe, it

is advisable to use it near its heel and vice versa, thusdistributingthe wear more uniformly than otherwise would be the case,and consequently increasing the life of the tool. I

Another important advantage of my invention relates to the means,hereinafter to be more fully described, whereby I may incline the stockat any angle to the saw. 7.

In the drawings: Figure 1 is a top view of my vise. Fig. 2 is a sideelevation of the same. Figs. 3 and 4 are a sectional elevation andsectional plan view respectively, of my new adjustable aws.

In the drawings, 1 represents the bed plate of the machine which ispreferably provided with horizontal slot or key-way 2-, and further witha series of equally spaced recesses 3. Slidably mounted in the key-way2, pref erably by means of T-head bolts 4, are a pair of carriages 5 and6. The invention asdisclosed shows these two carriages as specifically'diflerent, although it may be understood that each thereof, could ifdesired, be made like the one upon the left in Fig. 2, now to bedescribed.

' Carriage 5 is provided with a lock bolt? which may be dropped into anyone of the holes 3, as shown, whereby the carriage may be locked at anypoint within the rangeof the bed plate 1. A similar construction isadopted with regard to the carriage 6. Once adjusted these carriages maybe tightened to prevent their jarring, vibrating or lifting, by means ofbolts 4. Dove-tailed upon the carriage5 is a carrier 8 which may be,slidably adjusted upon the carriage 5, through the intermediary of thescrew 9. This carrier 5 has the same function and is broadly simllar tothe face portion of carriage 6 and it is to be understood that the jawsand ad-' ustingineans upon the carrier 8 are each similar to thecorresponding mechanisms upon the carriage 6, one only of these mechanisms will, therefore, be described. The

carrier 8 has a cylindrical face 9, preferaperture, in which is locatedthe bolt 10, is

another threaded aperture for the reception of the bolt 18 which isturned down at its lower end to provide a cam face 14. A vise jaw 15 hasa cylindrical back of the same radius as the cylindrical face of thecarriage 8 and is also provided with corresponding teeth or serrations.This vise jaw has moreover aT-slot 16 therein, which receives the T-headof the bolt 10. It is to be understood that both jaws and their securingmeans are identical, the jaw 15 merely being mounted upon a movablecarrier upon carriage5, whereas, the jaw 15 similar in all respectsthereto is mounted upon the carriage 6. The same reference numerals havebeen used to indicate the corresponding parts of the two aws.

In operation, it is to be understood that, inasmuch as both the carriers5 and 6 may be moved independently, they may be adjusted at any distanceapart and at any place along the bed plate. Inasmuch, further, as thescrew 9 gives a range of move ment greater than the space between twoconsecutive recesses 3, in the bed plate, it'is obvious that any stockof any size may be held at any point along the bed plate. If it isdesired to hold stock at an incline, such as is suggested by dottedlines in Fig. 1, the

screw 13 is loosened, wherebyby reason of the cam faces 12 and 14, theT-head or bolt 10 is also loosened, thereupon, the jaw 15 may be turnedto any position desired, the head of thebolt 10 sliding in the slot 16.Thereafter by screwing down the screw 13, the boltlO is forcedbackwardly by reason of the cam face mentioned, and with the furtherhelp of the serrations in the back of the vise jaw upon the face of thecarrier, the vise jaw is held rigidly in any position. It is obviousfrom the drawings taken I from the precise form thereof without departing from the scope of the invention in connection with thedescription above how stock may be clamped'between the vise aws Havingnow particularly pointed out and specifically described my invention,but Wishing it clearly understood that many departures and variationsmay be made which is more truly bounded and defined by the claims heretoappended, I claim 1, In a vise, a bed-plate, a pair of carriages mountedthereon and in opposed re: lation to each other, means for independentlyadjusting thecarriages, at a plurality of points along the bed-plate,said bedplate having recesses in the bed-plate, a lock-bolt passingthrough each carriage and engaging a recess in the bed-plate, a carriermounted upon one of the carriages, means to tightly secure the carrierand its carriage to the bed-plate, means to tightly secure the othercarriage to the bed-plate, work-engaging jaws attached to the carrierand the opposite carriage, means for causing said jaws to relativelyapproach or recede from each other through a range equal to the distancebetween any adjacent pair of recesses in the bed-plate to grip articlesof different sizes, the jaws, one carrier and the opposite carriageformed with inter-engaging serrations,

- and means to retain the carrier and its jaw and the opposite carriageand its jaw in locked relation to each other.

2. In a vise for hack saws, a support, a carrier along sa d support,sald carr er having a serrated cylindrical face andapain of crossedapertures, one thereof-bomniumeating with said face, a serrated jawhaving a serrated cyllndrlcal back to cooperate with the cylindricalface of the carrier, a T-slo't in the back of said jaw, a T-head boltengag ng the T-slotan'd having a camm'ed'aperture slldably mounted inthe aperture com- 11 unicating with the face of the carrier, an-

other bolt threaded in the other aperture and having an inclined portionfor coopera.-' tion with said CMXHIIGCl'POItIOH all for the a T-slottherein, a T-b'olt slidable in said carrier and cooperating with saidT-slot, means for longitudinally moving said bolt, whereby said swiveledjaw may be firmly clamped in adjusted position or released therefrom.
